Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

A balanced Y-connected load of (300 + j100) Ω is supplied by a three-phase line 40 km long with an impedance of (0.6 + j0.7) Ω per km (line-to-neutral). Find the voltage at the receiving end when the ...

Some industrial applicationsrequire you to feed a low-powerdc/dc converter from a three-phasesource and possibly to deal with line-tolinevoltages of 200 or 400V rms.Further, the neutral terminal of ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...
